Achieving high-resolution MR-Elastography images of the breast is a challenge due to shear wave attenuation and shadowing effects in breast tissue resulting in loss of wave energy and hence poor signal to noise ratio. We present a novel breast transducer set-up to ensure complete wave penetration throughout the entire breast. Waves reach even far upwards to enable quantification of axillary lymph nodes. Mechanical vibrations are generated via a novel concept utilizing an eccentric rotor that yields inherently constant amplitude with driving frequency. Volunteer results of wave speed and attenuation at 2mm isotropic resolution are presented including the axilla region.
